We can "almost" assure you that your town, wherever you are from, does not have a geyser (a hot spring) that can hurl boiling water up to 70 meters into the air. Well we do have one, and it is called Geysir. And if you are planning on seeing Geysir, you might as well stop at Gullfoss which is the largest waterfall in Iceland. Combining the both in the same trip is known as "the Golden Circle".
